1 398 284; Specification of Letters Patent. Pgrtqgntgfl Hwy, 22, 19231,

Application filed October 20, 1820.

To all whom it may concern.

Be it known that l, J ACOB A. SoHowAL'rnR, a citizen of the UnitedStates, residing near Newton, in the county of Harvey and State ofKansas, have invented a new and useful Headed-Grain Stacker, of whichthe following is a specification.

My present invention is a portable hoist, particularly for loading andunloading, stacking and transferring headed grain, hay and fodder frombarges, wagons, barns, and the like, or handling the material directlyon the ground.

The principal object of the invention is to produce a hoist of theabovementioned type which is simple in construction, economical toproduce and which is effective and etlicient for its purposes.

One of the main features of the present invention resides in the mannerin which the derrick or hoist may be collapsed to enable it to be movedunder telephone and tele graph wires and under shelter of the ordinarybarn sheds.

The invention further resides in the sundry details of construction,combination and arrangement of parts hereinafter more fully describedand pointed out in the appended claims. 1

In this specification and the annexed drawings, the invention isdisclosed in the form in which it is considered to be the best, but theinvention is not limited to such form because it is capable of beingembodied in other forms; and it is to be understood that in andby theclaims following the description herein it is intended to cover theinvention in whatever form it may embody within the scope thereof.

in the drawings:

Serial No. 413,148.

Fig. 8 is a plan view of the turn-table for the mast, and i Fig. 9 is afragmentary detail view in perspective of the catch member between theturn-table 19 and bearing plate 17 when the mast is collapsed as shownin dotted lines Fig. 2.

Referring particularly to the drawings: the hoist comprises a portablebase frame 34, to rest upon the ground and provided with side runnersat, having at its forward end traction wheel 28. Arranged-over theforward end portion of the base frame is a circular bearing ring 17supported in position by the uprights or standards 35 rising from thebase frame and secured in downwardly depending channel sockets b onthering. A mast 36 is provided for the hoist, and may be of any suitableconstruction, however in the present instance is. shown as constructedof side members 0 connected in spaced relation by spacing blocks (Zarranged at an intermediate point of the side members. Disposed betweenand secured to the lower ends of the side member 0 of the mast is aspindle c which is nor-. mally received in a'socket 14 secured to theforwa rd end bar f of the base frame 34. The upper ends of the sidemember 0 of the mast converge and are held in substantiallyjuxtarelation by the strap member 8 extending over the ends of the sidemembers. lhe mastextends -through an opening 19 in a turn-table 19,which is secured to the mast intermediate its ends, as shown in Figs. 1,7 and 8, by means of fastenings members extending through flanges 19 ofthe turntable.

The turn-table 19 rests upon the ring 17 and rotatably supports the mastin conjunction with socket 14L against lateral movement. The mast isfurther supported in position against lateral movement by guycables 37secured at one end to a swivel 7 on a spindle 3S, projecting upwardlyfrom the strap 8 of the mast. Tic other ends of the guy-cables securedin any suitable manner. such as by stakes, to the ground.

T he mast strengthened on its rear face 7y a truss rod 12 secured at itsupper end .o a stirrup 11 arranged over the top end 0. he mast. and atits other end to a U shapen trap or stirrup 13, secured to the lower endJortion of the mast considerably below the sion on the rod. This rod 12is spaced at an intermediate point in its length from the mast by ablock or bridge 39. A boom has one end secured to the mast between theside members 0 thereof, by means of a stationary pivot 41, locatedsubstantially midway between the top end of the mast and theturn-table19.

The boom 40 consists of spaced and substantially parallel side members'9 maintained in spaced relation by a spacing memher it. The outer endof the boom has a stirrup 3 extending around its end and side faces, asshown in Fig. 6, and secured to the boom by means of a bolt 6 extendingtherethrough.

The outer end of the boom 40 is raised and lowered by means of a cable 5having one end secured to a yoke 4 connected to opposite ends of thebolt 6.

The cable 5 passes ver pulley 10, secured to the upper end of the mast,and extends downwardly to a drum 21 secured to the lower end of the mastby means of brackets 20 and 22. The drum 21 is operated by the usualhand-crank 23, and may be held against unreeling rotation by anysuitable means such as a pawl and ratchet.

A sling 42 is suspended from the outer end of the boom by means of ahoisting c1.- ble 43 having one end secured to the sling and passingbetween the block-and-tackle 44 suspended from hooks 1 disposedadjustably in notches 45 in the outer top surface of the boom, and theblock and tackle 46 connected to the sling. From the blockand-tackle 44the cable 43 passes to a pulley 47 journaled between the side members. 0of the mast and immediately below the boom pivot 41. From the pulley 47the cable 43 passes downwardly to a pulley 48 secured to the end bar fof the base frame. The cable 43 may be operated either manually, or bydraft or motive power in a manner which is well understood. 1

In order to permit the hoist to be knocked down with the outer end ofthe boom resting; ,n the base frame 84 so that it may be stowed away, orto permit its passage under low trees and the like, the turn-tablebearing ring; 17 is formed on its front side with an arcuate opening 17substantially the width of the mast at that point, and the socket 3.4 ispr vided with a removable side The spring 13 is interposed between wall15, see Figs. 3, 4 and 5, thereby permitting the mast to be pivoted onthe bearing; ring 17 and moved to. the position shown in dotted lines inFig. 2. The wall 15 of the socket 14 is maintained in position by pins16.

Of course, to accomplish this the mast is rotated 180 from its full lineposition shown in "Figs. 1 and 2.

The turn-table 19 is provided with a laterally projecting lug 33 formedwith a concaved face 00 adapted to engage'in the stirrup 18 provided onthe rear side of the hearing ring 17 The member 33 engaging in themember 18 prevents accidental displacement of the mast when in theposition shown in dotted lines in Fig. 2, and also acts as a pivot uponwhich the mast will fulcrum whenreturning it to its upright or full-lineposition. 7 p

The wheels 28 of the hoisting rig are mounted on laterally extendingsupporting axles 29, as shown in Figs. 1 and 2, the axles being pivotedat points 30 in the front end bar 7 of the base frame to swing vertical.

Levers 24 are arranged on each side of the base frame and pivotallysecured thereto, as at 27, and overlie the axles 29. The other ends ofthe lever 24 are provided with fasteners 25 engageable in a complementalfastening member 26. It is therefore understood that when the fasteningmembers 25 and 26 are engaged, the lever 24 will lie substantiallyparallel with the side members a of the base-frame, and bear upon thedistal end of the axles 29, so as to raise the frame member above theground and support its forward end on the wheels.

As will be clearly understood, with the parts in the position shown inFigs. 1 and 2, the entire base frame rests fully upon the ground inorder to give a substantial and firm base for the hoisting rig when inoperation.

From the foregoing, it will be clear that the present invention providesa hoisting rigwhich may be readily collapsed and of a light constructionin order that it may be portaged, and at the same time providing onehaving great durability and economical to produce.
